Tool holder



aten'te Apr. 17, 19236 i ill iii Application filed April 28,

To all whom it may concern:

Be it known that 1, CHARLES A. Hunsrrs, a citizen of the United States,residing at Elmhurst, in the State of New York, have invented certainnew and useful Improvements in Tool Holders, of which the following is aspecification.

The present invention relates to tool holders, and the object is toprovide effective means for securing a tool in the holder, so that itwill not become accidentally dis placed.

In the accompanying drawings Figure 1 is a view partly in section andpartly in elevation of the holder,

Figure 2 is a detail sectional view with the holding means detached, and

Figure 3 is a perspective view of the key.

The holder comprises a stock 4 having a terminal head portion 5, throughwhich passes a socket This socket is adapted to slidably receive a tool,as illustrated at 7. At one side of the socket 6 is formed akey-receiving chamber 8 that is in communication with the socket 6, andhas its outer end tapered as shown at 9. Its rear end is offset asillustrated at 10 and opens through the rear portion of the head on theopposite side of the stock to the rear to end of the socket 6.

A key 11 driven into the chamber from the rear end thereof has its frontportion ofiset and is preferably tapered as shown at 12, so as to fitinto the tapered portion 9 of the chamber, thereby acting as a wedge.

A set screw 13 threaded into the head bears against an intermediateportion of the key 11 and serves to clamp the same snugly against thetool.

As further disclosed in the drawings, the bottom face or that portion ofthe key which bears upon the tool 7 is roughened or knurled as indicatedat 14, thus serving as a positive gripping face for,the tool. By

1921. Serial in. 465,170.

this arrangement, it is apparent that the increased contact between thewedge and the tool causes the pressure for holding the same to beequally distributed, thereby preventing the tool from breaking when itbecomes short and prolonging its period of use.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion and minordetails of construction, may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention what I claim as new, and desireto secure by Letters Patent, is

l. A tool holder comprising a stock having a tool-receiving socket and akey chainher at one side of the same having an oiiset portion openingthrough the stock, a key in the chamber adapted to bear against the toolplaced on the socket and having an of"- set portion in the offsetportion of said key chamber, and a set screw threaded in the stock andbearing against the key.

2. A tool holder comprising a stock having a tool-receiving socketopening through the end of the stock and through one side of the saidstock, a key-receiving chamber in communication with the socket andopening through the opposite side of the stock to that through which thesocket opens, a key in said chamber, and means for clamping the 80 keyagainst a tool placed in the socket.

In testimony whereof, I afiix my signature in the presence of twowitnesses.
